Table 14
Register Description Default value
4146 Device address for Modbus TCP/IP protocol 1

The device address is the address of the device for Modbus TCP/IP
protocol and is not a value equal to a address value for Modbus RS485
protocol (Modbus network address register 4100). Setting the parameter
"Device address for Modbus TCP/IP protocol" of the meter to the value
"255", the meter will skip the address analysis in the frame of Modbus
protocol (broadcast mode).
11 MAP OF ND30 METER REGISTERS
In the ND30 meter, data are placed in 16 and 32-bit registers. Process
variables and meter parameters are placed in the address area of registers
in a way depended on the variable value type. Bits in 16-bit register are
numbered from the youngest to the oldest (b0-b15). The 32-bit registers
contain numbers of float type in IEEE-754 standard. 3210 byte sequence -
the oldest is sent first.
